showin odifications of the retaining the drawings, the saidfinountingor's ippolft6 means. at the inward end of the spindle orr'od' 'is 7 is a View in horizontalsection of the for ned witlrran'elongated tapered socket moijinting or support at the inner end of the which receives the correspondingend-porpickenspindle or rod, and the renewable tion of the spindle cried, and; such end-porpin- 90 tion' of the spindle or rod is formed correspondingly so as to terminate in an elongated taper fitting the socket, as illustrated best in Fig. 7, in order that the said endportion may fit properly within the said tapered socket and have elongated hearing contact with thewall thereof. The converging portions of the wall of the taperedsocket serve to limit the extent to which the tapered spindle end can enter into the socket, and consequently the tapered socket constitutes and end-stop for the spindle or rod. In the drawings, the mounting or support 7 at the outward end of the spindle or rod is formed with a hole therethrough of a diameter corresponding closely with that of the spindle or rod, so that the end-portion of the spindle or rod fits snugly within. the said hole. In the drawings, also, the said. mounting or support 7 is provided with adjustable means such as aforesaid arranged, etc., to act against the outward end of the spindle or rod, axially of the latter. Several forms of such adjustable means are shown in the drawings, all being on the order of screw devices; still other forms may be employed, including devices of other types as well. In the case of the illustrated embodiments of the invention, the adjustable means is in screw-threaded engagement with the mounting or support 7, and is essentially what may be termed a screw adjustment device. In these particular instances the wall of the hole in mounting or support 7 is screwthreaded, and the adjustment device, or at least its acting portion, is a screw and is entered and screwed into the said hole. Usually, the in ner end of the said screw engages directly with the end of the spindle or rod, as shown, although this direct engagement is not'material. The serewmay be screwed inward, as

may be required, in making adjustments to cause the inward end of the spindle or rod to engage with the end-stop, and hold such end. .in contact therewith, and may be screwed outward, (and ctnnpletely removed when necessary,) in order to loosen the spindle or [rod and to permit its removal when desired.

In Figs. 1, 2, 4,2111Cl 5, the adjustment device is a headless screw 11, which 1s screwed completely into the hole or passage of the mounting or support 7. I find it advisable to employ locking means in connec-.

.tion with the adjusting screw '11, for the purpose of preventing accidental unscrewing of the latter as a result of the jarring and vibration in the case of the lay and the parts carried thereby, while the loom is in operation. The locking means in Figs. 1,

2, and 4, is a headless screw 12 which is screwed into the passage or socket 10 in the mounting or support 7, until the inner end cular recesses for the reception of a convenient tool or key used for turning the same. In the ease of the construction shown in F i g. 5, the locking means is a machine-screw 17 having a polygonal head adapted to have of the lay of a loom forward and backward during operation have a tendency to cause transverse vibrations of the picker-spindle or rod in forward and rearward directions. These vibrations tend to cause wear of'the sockets or holes that are occupied by the end-portions of the said spindle or rod. 'As wear progresses, it permits forward and rearward play of the picker-spindle endportions, such play increasing in extent as the wear of the walls of the sockets or holes progresses. One feature of my invention consists in a socket-piece which is detachably applied to a loom-lay, and which may be removed when wear has occurred, and replaced by a fresh one. The drawings illustrate this feature of the invention as employed in connection with the mounting or support 6. Thus, in Figs. 2, 3, and 7, a bushing 8 is shown applied to the mounting or support 6 in a manner providing for ready and convenient application and fastening, or unfastening and removal. The mounting or support 6 is formed with a hole into which the body of the bushing 8 fits. the bushing having a flange 9 which makes contact with one side: of the said mounting or support. and the bushing body being serew-threaded and having applied thereto a nut 81. which is tmrned up against the opposite side of lhemounting or support ('3. in order to fasten the lmshing in place. The nut 81 may be unscrewed from the bushing when it is desired to-rem'ove the latter. The socket or seat for the corre sponding end-portion of the picker-spindle or rod 4: is formed in the bushing 8. In Fig. 7 the said socket or seat is shown as tapered, as described hereinbefore. As will be apparent, a similar renewable bushing may be combined with the mounting or support 7. I

\Vhat is claimed as the invention is 1. The combination with a picker-spindle or rod having one end thereof terminating in an elongated taper, and supports at the opposite ends of said spindle or rod by which the latter is mounted upon the lay of a loom, of a men'iber removably combined with one of said supports, having a seat correspondingly tapered and fitting the said tapered end, and an adjustment screw in connection with the other support abutting by its inner end against the proximate end of the spindle or rod and by which the latter may be controlled endwise to keep the ta pered end properly engaged with the tapered seat.

2. The combination with a picker-spindle or rod, and supports at the opposite ends thereof by which the spindle or rod is mounted upon the lay of a loom, one of said supports having a hole therethrough, of an externally screw-threaded bushing 00- cupying such hole, fitting the corresponding end-portion of the spindle or rod and providing an end-stop therefor, and also having an external shoulder in engagement with one side of such support, a nut upon said bushing engaging the other sideof said' support, and adjustment means in connection with theother support by which the spindle or rod is adjusted endwise into engagement with said end-stop.

3. The combination with a picker-spindle or rod having one end thereof tapered, and

supports at the opposite ends thereof by side of such support, a nut upon said bushing engaging the other side of said support, and adjustment means in connection with the other support by which the spindle or rod is adjusted endWise into said tapered seat.
